I've always found it both disgusting and a bit amusing, the way people get so angry and upset when you dare to suggest that maybe they are not victims, maybe they actually could assert some control over the problem they're having. The earlier posts in this thread did not deserve a "-1, Troll" moderation. Stating what you actually believe in a sincere manner is not trolling. It's not a "-1, MakesMyDenialUncomfortable" mod for fuck's sake.
Everyone I know who successfully lost weight and kept it off for years did it by making permanent, sustainable, healthy changes in their lives. A few of them learned to like veggies and other healthy foods. Others did that and also formed the habit of regular exercise. The point is to consume fewer calories than you burn until you reach a new equilibrium. Like so many other things that upset people, this works every time it's properly tried.
